Hybrid Tea rose plant named `Seltantalium`

ABSTRACT

A new rose variety of the Hybrid Tea class, characterized by its continuous production of red/purple large flowers, borne singly on upright stems on a bush of medium height (120-150 cm) and that is especially suitable for growing in Latin America considering the prevailing light intensity, day length and seasonal effects.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the Hybrid Tea class, which was originated by me by crossing the variety `Tineke`, which is subject of U.S. Plant Pat. No. 8,055, with an unnamed seedling (SR 4063).

The primary objective of this breeding was to obtain a new large type rose with a good presentation and bud shape in different colors. The main difference between its parent `Tineke` is its red/purple color of the flower. The other parent (SR 4063) is not able to perform well in Latin America and has less rapid flowering cycles. Among the novel characteristics possessed by the new variety which distinguish it from all other varieties of which I am aware are:

(1) A vary large flower and flowerbud.

(2) The red/purple color of the flower.

(3) Rapid flowering cycles.

(4) Suitability for growing in Latin America.

(5) A vigorous upright plant of medium height (120-150 cm).

Asexual reproduction of the new rose variety by cutting and grafting using R. canina `Inermis` as rootstock, as performed in a greenhouse in Quito, Ecuador, shows that the aforementioned characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The new variety of rose plant is illustrated by the accompanying photographic illustrations, of which:

Sheet 1 shows a full face view of the flower and

Sheet 2 shows a typical specimens of the vegetative growth and flowers of the new variety in different stages of development and as depicted in color as nearly true as it reasonably possible to make the same in color illustrations of this character.

The following is a detailed description of this new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color description herein refers to plate numbers in the aforementioned color chart e.g. "55C" is plate "55C" of The Royal Horticultural Society Colour Chart.
